| Within the rapid development of the world economy,all fossil energy become exhausted and environment go worse.The awesome challenge in 21th century is finding massive clean energy which is sustainable.In future development of the world economy,renewable energy such as solar energy wind energy and biomass energy will play a more important role.As an outstanding representative of renewable energy,solar energy has many advantages suitable for modern society,for instance,sustainable,universal,and pollution free without carbon.Certainly it also has defects : Intermittent variability,low density and expensive in translation equipment.So that is an extreme important issue to research how to improve the efficiency of solar energy.My text purpose to decrease the ripping angle between solar ripping light and the moving solar panels promote the gathering efficiency of solar energy to reduce the cost of photovoltaic power generation.My text consult available solar tracking patterns,follow the basic law of solar motion,to analyze the trend mode of solar tracking(dpending on the day to track?potoelectric tracking and so on).This text offer to use movable equipment to track solar to expand the offensive range of solar tracking equipment,it is totally different from the regular mode of settled equipment.My text mainly research as follows,use GPS module to fetch the time date longitude and latitude of moving solar panel,We can get the number of the high angle and azimuth angle of the sun,use the inclination module to fetch these angle of solar panel,Compare the difference of both,controlling the stepper motor to rotate the panel toward the sun.The final purpose is to improve the efficiency of solar energy with solar panel settled in portable equipment.After the final test,the mobile tracking mode compared with the fixed track mode only lower 3%-8% power generation efficiency.It could use as power supplement or back up power in field operation of field exploration vehicle and sea-boat. |
